Handle indexed part select in continuous assign.
...
Non-constant indexed part select in continuous assignment generates
a select node with the correct width. In the process factor out and
share some of the part select calculations with expr part select
handling methods.

Fix runtime crash dumping VCD
...
Words of net arrays were incorrectly added to the scope. They should

Fix code generation for real expressions
...
Real value are vector width of 1, fix real literal to reflect this.
fix leaking real registers in code generation for function arguments.
Load of signal should handle conversion from real to vector. Function
arguments, type vector passed a real value, are an example where this
comes up.

Do not process back-slash escapes twice.
...
Backslash-escapes are processed early, during elaboration, so that
escaped characters show up in all places with the calculated value.
This means the $display formatting will get processed strings and
should not process back-slashes again.

Make sure parameter expressions are evaluated losslessly, as if
the l-value is unsigned and thus virtually infinite.

Careful not to lose bits parameter add expression

Parameter expressions that do not otherwise have a size should
evaluate expressions losslessly, expanding as necessary to prevent
